GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

VAR-201802-1044

Vulnerability from variot - Updated: 2023-12-18 12:37

A Stack-based Buffer Overflow issue was discovered in 3S-Smart CODESYS Web Server. Specifically: all Microsoft Windows (also WinCE) based CODESYS web servers running stand-alone Version 2.3, or as part of the CODESYS runtime system running prior to Version V1.1.9.19. A crafted request may cause a buffer overflow and could therefore execute arbitrary code on the web server or lead to a denial-of-service condition due to a crash in the web server. 3S-Smart CODESYS Web Server Contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. CODESYS is the core product of 3S-Smart Software Solutions GmbH. It is an IEC 61131-3 development environment for controller applications and CODESYS Control. It is a platform with a stand-alone system. Exploiting this issue may allow remote attackers to execute arbitrary code within the context of the affected application. Failed attacks will cause denial-of-service conditions. 3S-Smart CODESYS is a set of PLC (programmable logic controller) software programming tools. CODESYS Web Server is one of the web servers. CODESYS runtime system is a system for programming automation equipment

    "data": "A Stack-based Buffer Overflow issue was discovered in 3S-Smart CODESYS Web Server. Specifically: all Microsoft Windows (also WinCE) based CODESYS web servers running stand-alone Version 2.3, or as part of the CODESYS runtime system running prior to Version V1.1.9.19. A crafted request may cause a buffer overflow and could therefore execute arbitrary code on the web server or lead to a denial-of-service condition due to a crash in the web server. 3S-Smart CODESYS Web Server Contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. CODESYS is the core product of 3S-Smart Software Solutions GmbH. It is an IEC 61131-3 development environment for controller applications and CODESYS Control. It is a platform with a stand-alone system. \nExploiting this issue may allow remote attackers to execute arbitrary  code within the context of the affected application. Failed attacks will cause denial-of-service conditions. 3S-Smart CODESYS is a set of PLC (programmable logic controller) software programming tools. CODESYS Web Server is one of the web servers. CODESYS runtime system is a system for programming automation equipment",
